18 EC- GNDType Holder selection Tips for acing Important point for groove expansion Recommended chipbreakers M G G GA Max. machining diameter Min. machining diameter Choose a holder so the external diameter of the groove to be machined first can come in the maximum and minimum machining range of the said holder. If the first groove is within the valid machining diameter range, there will not be any limitations from the second and later passes. Important point for traverse turning: Min. machining diameter During groove expansion, if the first groove is within the valid machining diameter range, there will not be any limitations from the second and later passes. 2 Recommended chipbreakers M rom a holder rigidity standpoint, we recommend machining from the external diameter toward the internal diameter. External diameter side Internal diameter side eed direction Cutting point Internal diameter side External diameter side eed direction Cutting point Principal cutting force Principal cutting force When machining from internal diameter to external diameter, the principal cutting force takes up less of the insert so it will become less rigid. During face traverse machining, if the first groove is within the valid machining diameter range, there will not be any limitations from the second and later passes. Choose the lower limit of the recommended cutting conditions for the chipbreaker and straighten and discharge the chip. (In face grooving, broken chips can easily get caught in the groove and cause a problem.) Break chips by step feeding. Tips for Internal Diameter Machining Important point for internal diameter machining Recommended chipbreakers M G G If the prepared hole machining diameter is too small, use a low feed type chipbreaker M type or G type, that will make the chip curls smaller for efficient chip evacuation.

If there are any scratches or burrs on the insert seating surface, remove them. Install the insert by sliding it parallel to the seating surface. Clamp the insert to the opposite side of the cutting edge (holder side) while making it contact with the clamping surface. Tighten the insert to the recommended tightening torque. If it is made tighter than the recommended torque, the insert may break resulting in injury. Install the insert parallel to the seating surface lide the insert to the end.

If there are any scratches or burrs on the tool post, remove them. et the insert so that it becomes perpendicular to the workpiece. If the machined surface is bent, it may induce chatter. et the holder overhang as short as possible. When performing grooving or traverse machining, make the center height of the cutting edge as close to 0 mm as possible. (0.1 mm recommended) It may cause chatter if the center height does not match. When cut-off machining, make the center height of the cutting edge is within mm. ow center height will cause a larger burrs at the center.
